3 Claims.

lvIy invention relates to improvements in pencil Sharpeners, and has for an object to provide a pencil Sharpener consisting of a relatively large and heavy wheel mounted for revolution, in the axis of which are fastened the sharpening knives, and the operative revolutions of which require but the light puliing touches of the linger tips on the wheels periphery to sharpen any pencil contacting with the knives.

Another object of my improvement is to place two sets of oppositely disposed sharpening knives within the wheel to provide for sharpening a pencil extended into the wheel from either side thereof by relatively opposite revolutions of the wheel.

Another object of my improvement is to provide an open-top box, preferably of molded glass, in which are open-top bearings for mounting the said Wheel With the upper part thereof extended above the box.

Another object of my improvement is to design my device suitably for use as a paper weight thereby providing it for additional usefulness on a writing table.

Other objects of my improvement will appear as the description proceeds.

I attain these and other objects of my improvement with the mechanism illustrated in the accompanying sheet of drawing, forming a part of this specification, in which Figure 1 is a plan View of my pencil Sharpener, Fig. 2 is a side elevation of Fig. l, Fig. 3 is an end View of Fig. 2 in section on a medial vertical plane, and Fig. 4 is a side elevation of the wheel shown by itself.

Similar characters refer to similar parts throughout. Certain parts are broken away to show other parts hidden thereby.

With more particular reference to designated parts: The glass box 5 has the chamber 6 and the two aligned open-top bearings l; also there are two aligned holes 3 through the side walls of the box in the axis of the bearings "I, l.

The wheel 9 is relatively large and heavy, preferabiy of bronze and has the central opening 9a of smallest diameter at the center of the wheel and haring widely toward the sides thereof. On each side of the Wheel is fastened the gudgeon ID having the flange I2 which is attached to the wheel to dispose the axis of the gudgeon in the wheel axis. The gudgeon has the longitudinal central hole I I therethrough and the flange has the openings lS therein.

On the interior of` each of the flanges is fastened a pencil sharpening device of usual construction. That on the front flange I2 has the hollow conical body Ill while the one on the rear ange I2 has the hollow conical body I5. The conical body ifi has two longitudinal shavings slots I'l, only one of which is shown and two sharpening knives I6 and I8. I5 has two longitudinal shavings slots 2i), only one of which is shown, and two sharpening knives I9 and 2l fastened thereon.

The two point formers lli and I5 are alike, but are relatively oppositely disposed within the wheel and require relatively opposite revolutions of the wheel to operate as Sharpeners.

To operate: Place the end of a pencil in the front opening 8 and revolve the wheel 9 clock- Wise while forcing the pencil end against the l knives I6, I8. Because of the superabundant weight of the wheel and its easy movement in the glass bearings 1, 1, the pencil is quickly sharpened with little apparent effort required to revolve the wheel.

Then extend a pencil end into the rear opening 8 and revolve the Wheel 9 counterclockwise while forcing the pencil against the knives I9, 2l and the pencil is quickly sharpened as before.

The shavings cut from the pencils by the said sharpening knives fall into the flaring openings 9a and, as the wheel revolves, are carried out of the wheel through the flange openings I3 and fall into the bottom of the box chamber 6, from where they may be removed by first taking the wheel out of the box.

The wheel is caused to revolve, preferably, by placing the finger tips on its periphery and gently pulling them in the desired direction of revolution.

It may be noticed that both sides of the box are alike, and both sides of the wheel are alike. A pencil may be extended into that opening 8 which may be nearest and clockwise revolution of the wheel will sharpen the pencil.

Having thus disclosed my invention, what I claim as new therein and desire to secure by Letters Patent is,-

1. A pencil Sharpener including, a relatively large and heavy Wheel, mounted for revolution in bearings, having a central opening therethrough, and pencil-sharpening means fastened in the said central opening disposed for sharpening any pencil extended and retained therein by revolving the said wheel.

D 2. A pencil Sharpener including, a Wheel having a flaring central opening therethrough, hollow flanged gudgeons fastened in a line on each end of the wheel the flanges thereof having openings therethrough, pencil sharpening means The conical body 5 centrally disposed Within the said central wheel opening;i and means for mounting the wheel inl bearings on the said gudgeons for revolution.V

1 3. A pencil Sharpener including, a, Wheel hav-Y ing a. central opening therethrough flaring out-Y wardly fromrthe center of the wheel. hollow gudgeon on each end of the Wheel, aligned, hav-1V ing a ange with openings therethrough fastened* over the outer end of the flaring opening, a. pencil 10 sharpening device fastened to each of the said Wheel gudgeons therein to dispose the upper part of the Wheel outside of the boz, the said box sides having openings therethrough aligned with the said bearings, with the said hollow gudgeons when in the bearings and with the said pencil sharpening devices. i 1 Y l Y g VCLAUDE O.
